ANTIFRICTION-BEARING.

Patented Oct. 1c, 1917.

Application filed February 6, 1915. Serial No. 6,427.

To all whom it may concern: Be it known that I, FRANK Barman, a citizenof the United States, residin in the city of Philadelphia, county of .Philadelphia, and State of Pennsylvania, have in- I vented certainImprovements in Antifriction-Bearings, of which the following is aspecification.

My invention relates to ball bearings del0 signed for taking a thrust orcarrying a load acting transversely to the plane of the balls, and myleading object is to provide an improved. construction combining su.perior efiiciency, simplicity, durability and 16 economy. 3 I

The characteristic improvements of my invention reside rimarily in a'peculiar cage comprising,,1n its preferred form, a

pair of dished rings interlocked in'a plane or planes of the balls,which are held between them and project through apertures therein.

In the accompanyin is a sectional view ta en 01a bearing operativerelation; Fig. 2 is a sectional v i ew taken'through the axis of adetached ring embodying my improvements; 3 is an enlarged sectional viewtaken on the line 3-3 of Fig. 2; Figs. 4 and 5 are complementary dishedand apertured rings provided with flanges for locking them together'toform a retainer for the balls; Fig. 6 is a sectional view takenthroughthe axis ing a second form of m improvements in operativerelation; F1 7 is'a sectional view taken throu h the axis-of thedetached ring shown in ig. 6- Fig. 8 is an enlarged transverse sectional40 view of the ring shown in Fig. 7; Figs. 9

and 10 are plan views of dished and a ertured rings adapted to beinterlocke to provide the ball cage drawings, Figure 1 through the axis46 the rings shown-in Figs. 9 end 10 when brought into concentricrelation prepareto to bling the bearingil e bearing, in the form t ereoiillustrated in Figs. 1 to 5 inclusive, comprises the complements dishedrings 1 each provided with ova apertures 1, exterior flanges 1" andinterior fla 1, in combination with the balls 21ml 1n the des redcircular relation by the interlocked rm .56 and projecting through theapurtures, e

over the abutting edge of the embodying my improvements.

. of Fig. 8; and Fig. 11 is a transverse sectional view taken through.which it is used, or if, by reason of opposite surfaces of the ballsprojecting beyond the rings being adapted. for taking the thrust ortransmitting load between bearm s 3 containing the circular races 8.

he major axes of the' oval aperturesl, 60 before the rings are dished,are coincident with diametral lines drawn through the axes of the rings1 and these rings are-bent similarly away from a plane containing thecenters of the ovals, preferably, so that-the apertures in the ringswhen dished shall conform approximately to the ball contours, but itwill be understood that this is not essential.

' The flanges 1" and 1? are shown as approximate quadrants, so that theprojec-' tions of each ring will lie between oppositely extendingprojections of the complementary ring, each projection being turnedcomplementary ring. by which the rings are secured together firmly, withthe pro notion of the peculiar retainer of diamond-shaped or ap-.proximately oval cross-section.

The complementary rings being alike, theycan be stamped out of sheetmetal by a single die, dished by the same operation, and fixed togetheron the balls by the lap joints, without confusion commonly arisingwhere. differently constructed parts are to be assembled.

. In the form of the bearing illustrated in Figs. 6 to 11 inclusive,complementary dished rings 4 and 5, provided with the respective ovalapertures-4 and 5, are fixed 90 together by means of concentric flan s 4and 4 on the ring 4, such flan es emg turned over the concentric edges 0the ring 5 to form a cage for retaining the balls 6 which projectthrough the a ertures 4' and 5" intersecting the crowns o therings.

The cage thus'formed, of diamond or oval shaped cross section, retainsthe balls, which pro ect through the apertures beyond the rings, thebearing ring thus provided be ng 100 adapted for disposition betweenbearing 7 containing circular races 7 for. the

The retainer or retainers thus formed are adalpted for holding alubricant so that-it wil be taken up by the balls.

The form of the retainer is such that it will not contact with thebearings between wear or imperfect construction, contact is made, 110

{w 11 contact will be at the extremities of iihe pitch diameter of theballs or in the bjectionable: that is to say, while in com tructionscommonl used the lateralmove- 1 out or vibration o the retainer or thebeari gs on either side of it causes objectionable .rictional contactbetween the retainer and bearings, resulting in wear and noise, thesedefects are avoided by my construction'due'T-a ".to form.-pocket's,andballs disposed in said pocketsf'and projecting thro earings between wich it t t the fact that the retainer is drawn from its crowns throughwhich the balls reject away from the 7 atts, so that if by reason of anyfaultcontaict is made, such contact ween the crowns of the retainer andthejbott'oms off' the races, where leasti objectionabhu Havlng describedmy invention, I claim: 51. A ball bearing com rising a hollow an iularretainer that is iamond-shape in crziss-section, the inclined sides ofthe retainer having elliptical apertures with their maigr axessubstantially coincident with dia etral lines through the-center of theretainer, the apertures in one side being paired with the apertures inthe other side to fiorm pockets, and balls disposed in said pockets andpro ecting through said apertures. V

2. A ball bearing comprising a two part retainer composed of oppositelydished rings, each ring having oppositely inclined parts meeting at anang e and extending therefrom inwardly toward the other ring, the tworings being'joined at their edges to form a o with diametrallinesthroli'gh the centers of 7 the rings, the apertures in-ffo'ne ringbeing pairedwith the apertures in'the-other ring ugh said aperures.

3. A ball bearing com rising a hollow annular retainer that .isdiamond-shaped in How annular retainer, said I 'rings containingclliptical apertureshaving their major axes substantially coincidentcross section, the inclined sides of the retainer having oblongapertures with their greatest lengths transverse to the retainer, theapertures in one side being aired with the apertures in the other si eto form pockets, and balls disposed in said pockets and projectingthrough said apertures.
